Have Fun Storming the Ninja Castle!

Kaede castle upon release has had a major effect on any version it's been implemented into regardless of 10x drop rate or not. Economy-wise, that is. Just because it isn't under 10x rates doesn't make it s'hit or scarce. In fact, if it did get 10x rates it would be a little broken since we would have TONS of shield w.att scrolls.

@ above: Tonosama gives close to 50m exp? Dear god, it's going to be so overpowered post-BB.

Zipangu (Mushroom shrine and showa) did the same thing. But guess what it never did in GMS (to as great as an extent)? They're likely to water down the drops and quest rewards as they did to the rest of zipangu. Make it a nerfing trifecta. There's no reason they wouldn't. The best thing to predict future behavior is from examples of the past.
